Public methods
ViewCapture.captureToBitmap
@ExperimentalTestApi
@RequiresApi(value = 16)
public static final @NonNull ListenableFuture<@NonNull Bitmap> ViewCapture.captureToBitmap(@NonNull View receiver)
Asynchronously captures an image of the underlying view into a Bitmap.
For devices below Build.VERSION_CODES#O (or if the view's window cannot be determined), the image is obtained using View#draw. Otherwise, PixelCopy is used.
This method will also enable HardwareRendererCompat#setDrawingEnabled(boolean) if required.
This API is primarily intended for use in lower layer libraries or frameworks. For test authors, its recommended to use espresso or compose's captureToImage.
This API currently does not work for View's hosted in Dialogs on APIs >= 26, as there is no way to find a Dialog's Window. (see b/195673633).
This API is currently experimental and subject to change or removal.
ViewCapture.forceRedraw
@RequiresApi(value = 16)
@ExperimentalTestApi
public static final @NonNull ListenableFuture<@NonNull Void> ViewCapture.forceRedraw(@NonNull View receiver)
Trigger a redraw of the given view.
Should only be called on UI thread.
